METHOD OF SECURING THROAT-BRAGES.

Specification of Letters Patent.

Patented Dec. 9,1913.

Application fiIed May 2, 1913. Serial No. 765,180.

To all whom it may concern:

Be it known that I, J OHN F. Gnno, a citizen of the United States,residing at Newark, in the county of Licking and State of Ohio, haveinvented a new and useful Method of Securing Throat- Braces, of whichthe following is a specification.

My invention relates to an improved method of securing throat braces toboilers.

The primary object of the invention is the provision of means wherebythe brace may be quickly and accurately secured in position.

With the foregoing and other objects in view which will appear as thedescription proceeds the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings :-Figure 1 is an elevation partly in section. Fig. 2 isa sectional view showing the brace secured permanently in posit-ion.

In the usual method of securing throat braces to boilers a tap is usedfor threading the holes in the flue sheet and also the brace. Thetapping is done from the fire box side of the flue sheet and it is hardto secure an exact alinement between the aperture in the flue sheet andthe threaded opening in the brace. A considerable time is also necessaryin this method as after the tap has been threaded into the flue sheetand brace it is necessary to turn the same out again before the bolt canbe screwed into position.

It is the object of the present method to overcome these faults and inthe drawings the numeral 1 indicates the boiler shell, 2 the throatsheet and 3 the flue sheet of an ordinary locomotive boiler.

The numeral 4 indicates a throat brace of ordinary construction and incarrying out my method a tap 5 is used for threading the brace and whenthe brace has been threaded the tap is left therein and the operatingend 6 which is squared is inserted through the aperture in the fluesheet 3. The brace is temporarily held in position by means of the bolts7 and by applying a wrench or other device to the squared end (3 of thetap the same is then turned out through the flue sheet and threadingsimultaneously the aperture therein. As will be noted the tap tapersfrom the threaded end to the operating end. After the tap is removed thebrace is permanently secured to the boiler sheet by means of the rivets8 and a bolt 9 is then threaded through'the aperture in the flue sheetand into the brace.

From the above it will be seen that I have provided a quick means ofattaching the brace to the boiler and one in which the threaded aperturein the flue sheet and the threaded opening in the brace are in exactalinement and the bolt 9 can be easily threaded therein.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:

1. The herein described method of securing throat braces to boilersconsisting of primarily threading a throat brace and leaving the taptherein, temporarily attaching the brace to the boiler with theoperating end of the tap disposed through the aperture of the fluesheet, and then withdrawing the tap from the brace through the sheetaperture and threading the aperture during the withdrawal of the tap.

2. The herein described method of securing throat braces to boilersconsisting of primarily threading a throat brace and leaving the taptherein, temporarily attaching the brace to the boiler with theoperating end of the tap disposed through the aperture of the fluesheet, then withdrawing the tap from the brace through the sheetaperture and threading the aperture during the withdrawal of the tap,and finally permanently securing the brace to the boiler and threading abolt through the aperture and brace.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
